If you know a machinist there are dimensions in the adults only section as well.

thank you for the info. I think the part number I've been looking for has been updated. from my 40yr old manual.

looking at ebay shafts and like the price of the one piece shafts, but their unsplined.. is the splined shaft really necessary?

The alignment bar isn't splined, it's smooth everywere, just stepped down where it enters the gimbal bearing and the coupler... here's the specs from DonS' sticky

thanks for clearing that up bondo... someone I spoke with had mentioned that they were the same, but didn't give him much credit at the time.:very_drunk: shame one me..

this boat started out life blue also. puzzling thing is, it also had the mark 5 badging and railings with rear step ladder. which no longer exist. (drilled holes confirm )whiich I believe the mark 5 didn't come it blue. possible a previous owner cloned it ...who knows?
